$200 Answer from Writing Eqs
What is the equation of a line with a slope of -1/4 and going through the point (5, 3)
Calculate b: y = mx + b 3 = (-1/4)*5 + b b = 4.25
so the equation of the line is y = -1/4x + 4.25

$300 Answer from Writing EqsWhat is the equation of a line parallel to y = 1.5x + 4.5 and going through the point (-1, 3)?
Calculate b: y = mx + b 3 = (1.5)*-1 + b b = 4.5
so the equation of the line is y = 1.5x + 4.5

$400 Answer from Writing Eqs
What is the equation of a line perpendicular to the line y = 3x – 3 and going through the point (0, 0)?
First we find the slope of the perpendicular line 3m = -1 m = -1/3
Then the line is y = -1/3x
